Real Estate Excise Tax Information and Forms

Washington State, under Chapter 82.45 RCW, imposes an excise tax on the sale of real property. Unless otherwise specifically exempt from tax under WAC 458-61A, all sales of real property are subject to the Real Estate Excise Tax. If you have questions, please call (509) 477-5745.

A Real Estate Excise Tax Affidavit, along with a deed, must be presented to the Treasurer's office for processing and collection of tax or fees due. This is done prior to presenting the conveyance document (deed) to the County Auditor's office for recording.

Department of Revenue has created online affidavits which can be filled out using the links below. Each form is a four part form: Treasurer, Department of Revenue, Assessor and taxpayer copies. It is requested, but not required that all copies of the Real Estate Excise Tax Affidavit be formatted and printed on legal size paper. Signatures are required only on the Treasurer's copy of each form.
